'Stream' has not been declared

[stepanurban]

Hi, I'm getting following error when trying to compile ScanNetworksAdvanced example for Arduino nano 33 /home/.../Arduino/libraries/WiFiEspAT/src/utility/EspAtDrvTypes.h:61:30: error: 'Stream' has not been declared virtual uint8_t readRxData(Stream* serial, size_t len) = 0;

Where is the problem? How to get it? Thank you

Did you figure this out? I'm having the same issue.

Try with #include <Stream.h>

No luck.

Nevermind. User error. Accidentally deleted an entire function somehow.
